Аннотация: Microparticles made from degradable polyhydroxyalkanoates of different chemical compositions a homopolymer of 3-hydroxybutyric acid, copolymers of 3-hydroxybutyric and 4-hydroxybutyric acids (P3HB/4HB), 3-hydroxybutyric and 3-hydroxyvaleric acids (P3HB/3HV), 3-hydroxybutyric and 3-hydroxyhexanoic acids (P3HB/3HHx) were prepared using the solvent evaporation technique, from double emulsions. The study addresses the influence of the chemical compositions on the size and ?-potential of microparticles. P3HB microparticles loaded with doxorubicin have been prepared and investigated. Their average diameter and ?-potential have been found to be dependent upon the level of loading (1, 5, and 10 % of the polymer mass). Investigation of the in vitro drug release behavior showed that the total drug released from the microparticle into the medium increased with mass concentration of the drug. In this study mouse fibroblast NIH 3T3 cells were cultivated on PHA microparticles, and results of using fluorescent DAPI DNA stain, and MTT assay showed that microparticles prepared from PHAs of different chemical compositions did not exhibit cytotoxicity to cells cultured on them and proved to be highly biocompatible. Cell attachment and proliferation on PHA microparticles were similar to those on polystyrene. The cytostatic drug encapsulated in P3HB/3HV microparticles has been proven to be effective against HeLa tumor cells. В© 2013 Springer Science+Business Media New York.

Аннотация: The authors have constructed and characterized a series of membranes based on resorbable polyhydroxyalkanoates of different compositions. Five PHA types have been studied: a homopolymer of 3-hydroxybutyric acid, copolymers of 3-hydroxybutyric and 4-hydroxybutyric acids, 3-hydroxybutyric and 3-hydroxyvaleric acids, 3-hydroxybutyric and 3-hydroxyhexanoic acids. Scanning electron microscopy and atomicforce microscopy were used to examine the microstructure of membrane surfaces, showing that membranes based on the copolymer of 3-hydroxybutyrate and 3-hydroxyhexanoate had the roughest surface, while membranes based on the copolymer of 3-hydroxybutyrate and 3-hydroxyvalerate had the smoothest surface. The contact angle for water in air was smaller and hydrophilic properties better in the copolymer membranes than in the membranes based on the high-crystallinity homopolymer of 3-hydroxybutyric acid. The culture of mouse fibroblast cell line NIH 3,3 was used to test PHAbased membranes; results of fluorescent probes of DNA DAPI and the MTT assay show that membranes based on studied PHAs are not cytotoxic on direct contact with cells and are highly biocompatible; their adhesive properties and ability to maintain fibroblast proliferation are similar to those of polystyrene and better than those of polylactic acid membranes.

Аннотация: Molecular genetic methods were applied to study seasonal dynamics of species composition of bacterioplankton of two closely located flourishing and non-flourishing ponds. In both ponds observed are the same dominating species of free-living uncultured bacteria. It allows suggesting absence of substantial effect of cyanoprokaryotes flourishing on species composition of heterotrophic bacterioplankton dominants.

Phylogenetic diversity of winter bacterioplankton of eutrophic Siberian reservoirs as revealed by 16S rRNA gene sequences / M. Yu. Trusova, M. I. Gladyshev // Microbial Ecology. - 2002. - Vol. 44, Is. 3. - P252-259, DOI 10.1007/s00248-002-2020-1 . - ISSN 0095-3628

Аннотация: Using 16S rRNA gene sequence analyses we investigated the bacterial diversity of winter bacterioplankton of two eutrophic Siberian reservoirs. These reservoirs show similarity in phytoplankton community composition in spring and autumn but tend to differ in summer in exhibiting cyanobacterial bloom. Forty-eight unique partial 16S RNA gene sequences retrieved from two libraries were mostly affiliated with the class Actinobacteria, ? subdivision of the class Proteobacteria, and the phylum Cytophaga-Flavobacterium-Bacteroides. The clone library of the pond exhibiting summer cyanobacterial bloom showed more diversity in sequence composition. A significant number of bacterial 16S rRNA gene clones were closely related to freshwater bacteria previously found in different aquatic ecosystems. This finding confirms the assumption that some bacterial clades are globally distributed.

Аннотация: Genes encoding luminescence of Photobacterium leiognathi have been cloned in Escherichia coli. The luminescent clones were readily apparent. Among them, a clone containing a recombinant plasmid with a 13.5-kb insertion was identified. This DNA fragment contained all of the luminescence-encoding genes. The luciferase-encoding genes (lux) in this DNA fragment were localized. We have sequenced a part of the cloned lux region and identified the luxA, luxB and luxG genes encoding the ? and ? subunits of luciferase and a ? protein with an Mr of 26 180, respectively. The analysis of deduced amino acid sequences and comparison with known luciferase sequences from Vibrio harveyi, indicate the common origin of these proteins. В© 1990.

Аннотация: Expression of the lux-genes cloned on the recombinant plasmid pPHL7 (Ap rLux +) in Escherichia coli Z905 cells was studied in various environments, including model aquatic ecosystems. Expression of the lux-genes strongly depended on the nutritional status of the medium. In particular, the cultivation of cells in nutrient-rich medium favored the maintenance of the initial level of expression of the lux-operon, whereas nutrient limitation induced recombinant cell variants with an impaired control of the catabolite-dependent luxoperon. On the other hand, long-term laboratory cultivation of the recombinant strain in nutrient-deficient media or its long-term life in model aquatic ecosystems led to the accumulation of cells with a stringent control on the cloned lux-genes in the bacterial population. The presence of the selective factor (ampicillin) in the medium had no significant effect on the expression of the lux-operon.

Аннотация: An experimental approach for investigation of genetically modified microorganisms (GMMO) introduced into model ecosystems to evaluate potential risk of propagation of recombinant plasmids in surrounding medium has been developed. The object of modeling was Escherichia coli Z905 strain with a recombinant plasmid with bacterial luminescence genes, which was introduced into water microcosms of different structure. The approach involves comprehensive investigation of GMMO at four hierarchical levels: molecular (retaining the structure of the plasmid and expression of cloned genes); cellular (variation of metabolic activity); population (competitive power and metabolic interactions of GMMO with indigenous microflora, migration of recombinant and natural plasmids); ecosystem (effect of GMMO and cloned genes on ecosystem parameters). The experimental evidence and theoretical estimates are intended to form grounds to develop a basic version of an ecological certificate for different GMMO variants.

Аннотация: The influence of some chemical substances on luminous bacteria was studied to elucidate the interrelation between the xenobiotics action on bacterial luminescence and cell ultrastructure. Such substances as quinones, phenols, chlorides of heavy metals (in concentrations of substances inhibiting luminescence by 50%) resulted in damaging effects upon bacteria: a lot of cells had damage of membranes due to changes in their permeability. It was found that the high concentration of EDTA and toluene decreased the luminescence and caused the condensation of DNA-fibrils and the cell damage after long-term and short-term action. The low concentration of EDTA and toluene did not decrease the bacterial luminescence; the noticeable damage of cell membranes did not take place during short-term treatment. However, the long action of these substances changed the membrane permeability resulting in increased sensitivity of bacterial luminescence to some toxic substances.

Аннотация: The paper describes the production and investigation of flexible films made of high-purity polyhydroxyalkanoates (PHAs) - polyhydroxybutyrate [poly-(3HB)] and poly-3-hydroxybutyrate-co-poly-3-hydroxyvalerate [poly(3Hl3-co-3HV)], containing 4-30 mol % hydroxyvalerate. Poly(3HB-co-3HV) films have a more porous structure than poly-(3HB) films, which are more compact, but their surface properties, such as wettability and surface and interface energies, are the same. Sterilisation of the PHA films by conventional methods (heat treatment and gamma-irradiation) did not impair their strength. Cells cultured on PHA films exhibited high levels of cell adhesion. Cell morphology, protein synthesis and DNA synthesis were estimated by extent of H-3-thymidine incorporation into the animal cell cultures of various origins (fibroblasts, endothelium cells, and isolated hepatocytes) in direct contact with PHAs. The investigation showed that this material can be used to make matrices for in vitro proliferous cells. The investigated properties of poly-(3HB) and poly(3HB-co-3HV) films proved to be fundamentally similar. (C) 2004 Kluwer Academic Publishers.

Аннотация: A method for single nucleotide polymorphism identification was developed, which was based on the primer extension reaction (PEXT) followed by bioluminescent solid-phase microassay. Recombinant Ca2+-regulated photoprotein obelin and coelenterazine-dependent Renilla muelleri luciferase were used as reporters. The study was performed as an example of SNP genotyping of the human F5 gene encoding human Factor V Leiden polymorphism 1691 G -> A (R506Q). Genomic DNA was amplified by PCR using primers flanking polymorphic site of 140 base pairs. PCR products were used as templates for two PEXT reactions using two primers containing 3'-terminal nucleotides, which were complementary to either normal or mutant alleles. If the template and allele-specific primer were completely complementary, the latter was elongated with DNA polymerase. The resulting extension product contained biotin residue due to the presence of biotinylated deoxyuridine triphosphate (B-dUTP) in the reaction mixture. The products were analyzed using obelin-streptavidin conjugates. The optimal PEXT-reaction conditions were found, which ensured a high reliability of SNP genotyping. A new approach to simultaneously revealing both alleles in one well was developed using two bioluminescent reporters. The efficiency of the proposed approach was shown in the study of clinical DNA samples.

Oligonucleotide probes were immobilized on the surface of polymer methacrylate beads or microbiological plates of different types. A 30-mer oligonucleotide or its derivative with the biotin residue on the 3'-terminus, as well as a denatured double-stranded PCR fragment of the hepatitis C virus with the sequence of the 30-mer oligonucleotide was used as a DNA template. The probe in the hybridization complex was labeled by the elongation of the chain using a Taq DNA polymerase in the presence of biotinylated deoxyuridine triphosphate. The results of the bioluminescent assay were compared with the results of colorimetric analysis obtained with alkaline phosphatase as a reporter protein. It was shown that the use of the bioluminescent obelin label substantially accelerates the DNA detection procedure, provides a high sensitivity of the assay (no less than 10(-15) mol of DNA template), and ensures a quantitative determination of the amount of DNA template in the tested sample.

Аннотация: Strain AIS(T), an aerobic halophilic, Gram-reaction-negative, heterotrophic bacterium isolated from the water of Shira Lake in Khakasia, southern Siberia, was characterized using a polyphasic approach. Our analysis of the 16S rRNA gene sequences showed that 'Aliidiomarina haloalkalitolerans', 'Allidiomarina sanyensis', Idiomarina maris and AIS(T) formed a distinct lineage. The sequence similarities between AIS(T) and the type strains of species of the genera Idiomarina and Aliidiomarina were 91.6-95.1 % and 94.0-96.9 %, respectively. The major isoprenoid quinone of AIS(T) was ubiquinone 8 (Q-8). Predominant cellular fatty acids were iso-C-17:0, iso-C-15:0 and summed feature 9. The genomic DNA G+C content was 45.8 mol%. It is concluded that AIS(T) represents a novel species of the genus Aliidiomarina, and the name Aliidiomarina shirensis sp. nov. is herein proposed for it. The type strain is AIST (=JCM 17761(T)=BCRC 80327(T)). Based on its fatty acid profile and our phylogenetic analysis, we propose that Idiomarina mans be transferred to the genus Aliidiomarina.
